' To "dll whom it may concern:

Beit known 'that I, CHARLES P. DREssEL, 4a citizen of the United States, residing at .VVilkes-Barre, in the county of Luzerne and 5`State of Pennsylvania, have invented new and useful Improvements in Ash-Bumpers, o f which the following is a specification.

This invention relates to improvement-s in ash dumpers, and has particular reference to .a device of that kind adapted to be arranged within a firebox and at one end of the grate, in' such position, that a quantity of ashes moved toward the door will pass onto the def l.vice after which they may be dumped into the ash pit.

-, Another object is the provision of an ash dumper provided with a tilting platform and means for holding the same in a horizontal plane.

With' these and other objects in view, which will more fully hereinafter appear, the present invention .consists incertain novel details of construction and arrangement of parts, hereinafter fully described, illustrated in *the accompanying drawings, `and more vparticularly pointed out in the ap- 4 pended claim; itbeing understood that various changes in the form, proportion, size,

and minor details of the device may be made,"

within the scope of the appended claim, without departing from the spirit or sacrilicing any of the advantages of the invention.

In the accompanying drawings, formingV part of the speciiication; Figure 1 is a plan view of the device showing its application to a grate. Fig. 2 is a transverse sectional view on the line 2 2 of Fig. 1.' Fig. S is a similar View on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal sectional view on the line 4 4 of Fig. 1 and looking in the direction of the arrow.

Similar numerals of reference are.. elnployd to designate corresponding parts throughout.'

'The device about to be described is positioned at'the outer end of the grate, in an ordinary'fnrnace 'end-occupies the positin of the ordinarytdeadplata'it being under- 50 stood that the dead plate will be removed so as to provide an opening between the outer'end of the lirebox and ash pit.

The device as shown in Fig. 1, includes v a` rectangular-shaped frame, corresponding- I in area to the area ofthe dead plate of the boiler to which it is applied, the longitu- Specication of Letters Patent.

dinalfsides of said frame being designated by the numerals 5 and 6 and the opposite ends by the numerals 7 and 8. Positioned inthe frame is what willI subsequently be` termed a tilting platform designated by the numeral 9. This member corresponds in area, approximately, to the inner area of the frame and is provided `at' its opposite ends, and adjacent to what will subsequently be 65 termed its outer side, with a pair of dependingV lugs 10 and 11. The lugs 10. and 11 are provided with'transverse openings, which aline with similar openings formed in the ends '7 and 8, these openings receiving 70 pivot pins 12 and 13. By virtue of the piv` otal mounting of the platform 9, it will be manifest that the latter will normally de pend from the frame. It will be further observed, owing to the lpivotal connection 75 between the platform and frame, when the platform is in a horizontal position it willbe in a planewith the upper edge of the frame, and will occupy the position of the dead plate in an ordinary boiler.

In order to hold the platform in a horizontal position and then to release the same when a quantityy of ashes has been moved thereon, so that the ashes will be directed v into the ash pit, the following construction is employed By reference now to Figs. 1, 2 and 4 it will be seen that t-he outer side 6 of the frame is centrally provided on its opposite faces with bushings 14 and 15. The bushing 14,-eXtends through an opening in the shell of the boiler (not shown), and journaled in'the said bushings 14 and v15 is a shaft 16. The opposite ends of the shaft 16 extend beyond the bushings 14 and 15,'

the said extending end portions being non-l cylindrical in contour as shown at 17 and 18. Keyed or otherwise secured to the inner noncylindrical end of the shaft 16 isa cam stud 19. This member is best shown in Fig. 4 and comprises an oblong body preferably semi-ellipticalin contour. The distance between the shaft 16 and straight side of the body is such that when the cam is turned to one position the said straight side will be in 05 1 ofthe frame so that it will engage with the lower surface of the platform and hold the latter in a horizontal posit-ion, until the shaft 16 is turned, which is accomplished by means of a crank handle having a socket to receive the outer non-cylindrical end 18 of the shaft, whereupon the platform will descend7 so that ashes or other material placed- The combination'of a furnace dead plate` provided with an opening, a frame located in said opening, a platform of an area approximately corresponding to the inner area of the frame, said platform being formed upon its opposite transverse edges and adjacent its front edge with depending lugs,'

said lugs having openings, pivoted members carriedby 4the side of the frame engaging the said openings, the frame having its cen-k i esmas tral portion provided withbushings,a shaft 'journaled in said bushings and extending beyond the same, the extending portions of the shaft being non-.circular in contour, a

cam member upon the inner extending portion of the shaft, said cam. member contacting the platform beyond its pivots to sustain the same in a plane parallel with the frame when the said cam 1s 1n one position,`

and to allow the platform t`o tilt upon its pivots when the shaft is rotated to bring the cam toits lower position.

In testimony whereof I atx my signature in presence of two witnesses.
